A New Trick For Dexterity In Prosthetic Hands Researchers working on the next generation of prosthetic limbs have a few fundamental engineering problems to overcome. For starters, how can people using prosthetic limbs effectively signal what motions they want to perform? A team of researchers may have a solution: A surgical technique that uses muscle tissue to amplify the nerve signals. Participants fitted with prosthetic hands after this surgery, described in Science Translational Medicine this week, reported being able to manipulate objects with a degree of control and dexterity not previously seen. Electrical engineer Cynthia Chestek at the University of Michigan explains why this muscle…
